Question

how many pie bond and sigma bond in cyclopentane​

Answer 1

Answer:

There will be no pi bond in cyclopentane, as it as alkane and does not contain any double bond.

Answer 2

Answer:

There are 15 sigma bond and no pie bond present in cyclopentane.

Explanation:

Molecular formula of cyclopentane is $C_5H_{10}$.

Number of π bonds:

In the first scenario, we must count the unsaturated cyclic olefinic hydrocarbons' unsaturated carbon atoms (X) and unsaturated hydrogen atoms (Y). An aliphatic cyclic olefin's number of or double bonds can be determined using the following formula:

$P_c=\frac{2X-Y}{2}\\P_c=\frac{2 \times 5 -10}{2}\\P_c=\frac{0}{2}\\P_c=0$

Number of $\sigma$ bonds:

In the first scenario, we must count the unsaturated cyclic olefinic hydrocarbons' unsaturated carbon atoms (X) and unsaturated hydrogen atoms (Y). An aliphatic cyclic olefin's number of bonds can be determined using the following formula:

$S_c=\frac{3Y}{2}\\S_c=\frac{3\times10}{2}\\S_c=\frac{30}{2}\\S_c=15$

Among which 5 $C-C$ bonds and 10$C-H$ bonds present in this compound.
