Can anyone please give a clear explanation of whether the ease of hydrolysis of group IV tetrachlorides increase or decrease down the group? including the reasoning.

hey is OH an electron withdrawing group?

OH is an electron donating group

Ease of hydrolysis increases as the metallic nature of the elements increases.

You can try viewing it from the end on the left side. Then visualize them as clock faces, using references with H and CH3 at the 12 o'clock positions.

When A reacts with Br(qa) which group should we consider as the first one to put Br ? oh or c(ch3)3? And why?
Please help!! Thankyou

C(CH3)3 and OH both are electron donating groups.
Substitution will occur about ortho and para positions

Yes but with respect to which group?

Anyone has Examiner Report for Oct/Nov 2014?

Do you have a diagram of the compound? Or is it something you thought of?

diagram got deleted :/ Br(aq) with A
June 2013/41 was 5 c

It would be in the 2 and 6 position with respect to OH.

OH is a stronger activating group compared to alkyl groups, there is also the issue of the steric hindrance of the large alkyl group.

May I please get notes on nmr?

 

[mr dam bhai]

can someone explain me properly how to draw titration curves

Ok thnxx
