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.

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.
Write the name and formula of oxoacid of fluorine.
