mole % of 'C' in CH=   $\frac{mole\;of\;C}{mole \; of\; C + mole\; of\; hydrogen}\times 100$

= $\frac{nc}{n_{H}+n_{c}}\times 100$

For 1 mole of C, there are 4 moles of hydrogen

$\therefore n_{c}=1$ and $n_{H}=4$

$=\frac{1}{1+5}\times 100=20$%

Option 1)

75%

Option 2)

80%

Option 3)

25%

Option 4)

20%
