A) E2 is a concerted reaction in which bonds break and new bonds form at the same time in a single step.

This statement is correct. In an E2 reaction, the bond between the alpha carbon and the leaving group breaks, and a new bond between the alpha carbon and the base forms in a single step.

b) Order of reactivity of alkyl halides towards E2 dehydrohalogenation is found to be 3o.

This statement is incorrect. The order of reactivity of alkyl halides towards E2 dehydrohalogenation is actually 3o > 2o > 1o. This means that tertiary alkyl halides are more reactive towards E2 reactions compared to secondary and primary alkyl halides.

E2 is a concerted reaction in which bonds break and new bonds form at the same time in a single step. Order of reactivity of alkyl halides towards E2 dehydrohalogenation is found to be 3o > 2o > 1o. In E2 reaction both hydrogen and leaving group should be antiperiplanar and that’s why In E2 elimination different stereoisomer (diastereomer) converts into different stereo product.
