I am not Exactly against reservations, Reservations Uplift the Backward people but the Need of the hour is Change in the Pattern of Reservation rather than going completely against the removal of it.

Dear Friend, I am from IIT Madras presently doing Chemical engineering final year. I am a drop out, I just went through the placement process. I can ensure you with 100% guarntee that dropping doesnt matter much if you can make to the premier instiutes like IITs NITs. Hope this clarifies you. Absolutely no one asks you about the dropped out year

Guys answer is pyridine for sure.

Sodium has 11 electrons lets us look it this way because 11 is not stable format we i tends to have free electrons which carry current in the metal form where as in NaCl as Cl has 17 electrons it will take that free electron and get 18 electron configuration hence there are no free electrons which means no conduction

Any salt is hydrated means that ithas formed bonds with water molecules. For any hydration to take place heat of hydration should be greater than heat of breakage of bond in salt.
Now in NaCl and LiCl as anion is same only difference comes in cation. Li+ has higher charge density and which means more energy is realeased as heat of hydration for LiCl than NaCl hence more hydrated.

An oxoacid is an acid which contains oxygen. More specifically, it is an acid which: 1. contains oxygen; 2. contains at least one other element; 3. has at least one hydrogen atom bound to oxygen; and 4. forms an ion by the loss of one or more protons.[1]The name oxyacid is sometimes used, although this is not recommended.Generally, oxoacids are simply polyatomic ions with a hydrogen cation.Under Lavoisier's original theory, all acids contained oxygen. It was later discovered that some acids, notably hydrochloric acid, did not contain oxygen and so acids were divided into oxoacids and these new hydracids.

These elements are called transition elements as they show transitional properties between s and p-block elements.

After C - X bond is broken it forms X- and C+. X- ions gets hydrated in any protic solvent (protic solvents has H+ and we have X- as free ion so they attract and form bonds). When bond is formed energy is released that is more than C -X bond energy hence C -X bond is broken easily in protic solvents

The answer is (d). Here all the molecules have lone pair - lone pair repulsion. Larger the bond length lower is the bond pair bond pair repulsion because of the wide spread of bond electrons. Hence the answer is H2Te

(a) is the correct answer. Larger the bond length smaller is the bond energy. It is easy to break a bigger stick than a very small stick. As size of I > Br > Cl , order of bondlength is C-I > C-Br>C-Cl

as it is volume the units are same as volume m3

CCl4 is an example of what you have asked for C - Cl have Electronegitivity difference so that is a polar covalent bond but as a molecule it is nonpolar because it is exactly terahydral in shape and symetrical.Hence all polarity is cancelled.

* sorry i mean C has no magnitude in x direction
|
|
|
|
|
yes because B and Asina vector must cancel out as they resultant vector has magnitude in x direction

what step you didnt understand?

Ortho chlorophenol is stronger because ortho fluoro phenol will have H - bonging and hence Hydrogen is not free

Reynolds number has very importance in CHemical Engineering and is a Diemnsionless number that gives you an idea of type of flow in the system

Wow, what a neat question. I think it is related to the effect thatwe have seen when a skater who has arms extended and is slowly spinningsuddenly pullls the arms into the body surface. The result is thatspin rate increases. To even spin faster the skater will be standingstraight with the arms up over the head. This makes the distributionsof mass as close toe the spin axis as possible and makes the spinas large as possible. The main idea is that angular momentum is conseved, ie, cannot change. Angular momentum is the product of the spin rateadn the moment of inertia ( a measure of the distribution of the mass aboutthe axis of rotation) The product is constant. If mass is widely dispersedas before condensing into a planet, and is very slowly rotating, thenwhen it condenses into a planet (making a small moment of inertia) therate of rotation could be large. So condensing amplifies whateverrotation there was initially. NOw, what are the chances of somethingnot rotating exactly before it condenses? Apparently, very small sinceeverything seems to have some rotation. I am not sure this gets to yourquestion of why, but it has been a great question to think about. Thanks.
