Which halogen compound in each of the following pairs will react faster in SN2 reaction
(CH3)3 C – Cl or CH3 – Cl
Advertisements
उत्तर
CH3−Cl will react faster in SN2 reaction than (CH3)3 C−Cl, as CH3−Cl is a primary halide whereas (CH3)3C−Cl is a tertiary halide. Primary halides undergo SN2 reactions faster.

Which of the following is isoelectronic pair?
Give reason to explain why ClF3 exists but FCl3 does not exist.
Statement I: Acid strength increases in the order given as HF << HCl << HBr << HI.
Statement II: As the size of the elements F, Cl, Br, and I increase down the group, the bond strength of HF, HCl, HBr, and HI decreases and so the acid strength increases.
In the light of the above statements, choose the correct answer from the options given below.
