Solution

ClCH₂CH₂OH is stronger acid than CH₃CH₂OH because of:

– I effect of Cl increases negative charge on O atom of alcohol
– I effect of Cl disperses negative charge on O atom to produce more stable cation
– I effect of Cl disperses negative charge on O atom to produce more stable anion
None of these

Solution

Sodium methoxide and sec-butyl bromide.
Sodium ethoxide and sec-butyl bromide.
Sodium tert-butoxide and ethyl bromide.
Sodium methoxide and tert-butyl bromide

Solution

X and Y are identical mixture of CH₃I and (CH₃)₃C –OH
X and Y are identical mixture of CH₃OH & (CH₃)₃C–I
X is mixture of CH₃I and (CH₃)₃C – OH
Y is mixture of CH₃OH & (CH₃)₃C–I

Solution

By path 1 (CH₃)₃C–I and CH₃OH are formed and path 2 also form the same.
