प्रश्न
Which halogen compound in the following pair will react faster in SN2 reaction CH3Br or CH3I.
Advertisements
उत्तर
CH3I will react faster in SN2 reaction than CH3Br. This is because I− is a better leaving group, owing to its greater size than Br−. As a result, it will leave at a faster rate in the presence of an incoming nucleophile.

The reaction \[\ce{3ClO- (aq) -> ClO3- (aq) + 2Cl- (aq) + 2Cl- (aq)}\] is an example of
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.
