Question

Classify the following as primary, secondary and tertiary alcohols:

$A$:

$B$:

$C$:

$D$:

$E$:

$F$:

Answer 1

$A$:

In primary, secondary and tertiary alcohols, the $-OH$ group is attached to primary, secondary and tertiary carbon atom respectively.
In the given compound, $-OH$ group is attached to primary carbon and hence it is primary alcohol.


$B$:
In primary, secondary and tertiary alcohols, the $-OH$ group is attached to primary, secondary and tertiary carbon atom respectively.
In the given compound, $-OH$ group is attached to primary carbon and hence it is primary alcohol


$C$:
In primary, secondary and tertiary alcohols, the $-OH$ group is attached to primary, secondary and tertiary carbon atom respectively.
In the given compound, $-OH$ group is attached to primary carbon and hence it is primary alcohol.

$D$:
In primary, secondary and tertiary alcohols, the $-OH$ group is attached to primary, secondary and tertiary carbon atom respectively.
In the given compound, $-OH$ group is attached to secondary carbon and hence it is secondary alcohol.


$E$:

In primary, secondary and tertiary alcohols, the $-OH$ group is attached to primary, secondary and tertiary carbon atom respectively.
In the given compound, $-OH$ group is attached to secondary carbon and hence it is secondary alcohol.

$F$:
In primary, secondary and tertiary alcohols, the $-OH$ group is attached to primary, secondary and tertiary carbon atom respectively.
In the given compound, $-OH$ group is attached to tertiary carbon and hence it is tertiary alcohol.
