Answer 2

Answer:

The answer is $C_4 H_{10}$ and the name is Butane

Explanation:

As we know that $C_3H_8$ belongs to alkane groups.

The general formula for the alkane group is $C_nH_{2n+2}$

Hence n=1 the number of hydrogen atoms will be 4 i.e Methane ($CH_4$)

When the value of n=2, the number of hydrogen atoms will be 6

i.e Ethane ($C_2H_6$)

Therefore n=4, the number of hydrogen atoms will be 10

i.e $C_4H_{4*2 +2} =C_4H_{8+2}=C_4H_{10}$  and its IUPAC name is Butane

Butane is the next higher homolog of Propane($C_3 H_8)$.
