Find the correct stability order for the following carbocations:

What is the increasing order of stability for the following free radicals?

What is the correct order of stability for $1^\circ, 2^\circ, 3^\circ$ carbocations and benzyl carbocation?

In which case does the heterolysis of the carbon-chlorine bond lead to the most stable carbocation?

Match the List-$I$ with List-$II$:

$A$. Carbocation	$I$. Species that can supply a pair of electrons.
$B$. Carbon free radical	$II$. Species that can receive a pair of electrons.
$C$. Nucleophile	$III$. $sp^2$ hybridized carbon with empty $p$-orbital.
$D$. Electrophile	$IV$. $sp^2/sp^3$ hybridized carbon with one unpaired electron.

Choose the correct answer from the options given below:

Stability order of the following carbocations:
$(i) CH_3 - C^{+}(OCH_3) - CH_3$
$(ii) CH_3 - C^{+}(CH_3) - CH_3$
$(iii) CH_3 - NH - C^{+}H_2$
$(iv) CH_3 - C^{+}H_2$
