Multiple Choice QuestionsThe product Y for the below reaction is
C.
This is a carbalamine reaction. It gives isocyamide as main product.
The major product formed in the following reaction is:
C.
It is nucleophilic substitution reaction.
The product formed in the following reaction is
A.
The product formed in the above reaction is as follows-
The correct order of increasing reactivity of the following alkyl halides, CH3CH2CH(Br)CH3
(I) CH3CH2CH(Br)CH3
(II) (CH3)2CClCH2CH3
(III) CH3CH2CH2Cl and
(IV) Towards SN2 displacement is
I < II < III < IV
III < I < IV < II
III < I < II < IV
II < IV < I < III
D.
II < IV < I < III
The reactivity of alkyl-halides towards S2N depends on
(i) Degree of C-atoms: reactivity order 1° > 2° > 3°
(ii) Electronegativity of halogen: reactivity order I > Br > Cl > F
Hence, correct order is III < I < IV < II.
