Question

Which of the following statement is not correct?
(a) E2 is a concerted reaction in which bonds break and new bonds form at the same time in a single step
(b) Order of reactivity of alkyl halides towards E2 dehydrohalogenation is found to be 3° 2° < 1°
(c) In E2 elimination different stereoisomer (diastereomer) converts into different stereo product
(d) The E2 reactions give Saytzeff products​

Answer 1

Answer:

(d) is wrong

Explanation:

Saytzeff rule governs the orientation in SN1 reaction

Answer 2

Option c is not correct.

• E2 elimination is a concerted reaction in which the bond breaking and bond formation take place in a single step.
• The order of reactivity of alkyl halides towards E2 dehydrohalogenation is 3<° 2° < 1°.
• Again saytzeff products get predominated at E2 elimination due to the involvement of gama hydrogen.
• It is a stereospecific reaction.
