Cyclopentane is a cyclic hydrocarbon with the molecular formula C₅H₁₀. It consists of a ring of five carbon atoms, each bonded to two hydrogen atoms. The electron dot structure (Lewis structure) of cyclopentane can be determined by following these steps:

1. Determine the Total Valence Electrons:

» Each carbon contributes 4 valence electrons, and each hydrogen contributes 1 valence electron.

» Total valence electrons for C₅H₁₀ = 5 × 4 +10 × 1= 30 electrons.

2. Arrange Atoms in a Ring:

. Arrange the five carbon atoms in a ring.

3. Connect Atoms with Single Bonds:

» Form single bonds between each carbon atom and its adjacent carbon atoms to create the cyclopentane ring.

4. Distribute Remaining Electrons:

» Distribute the remaining electrons around the carbon atoms to satisfy the octet rule.

5. Check for Octet Rule:

» Ensure that each carbon atom in the ring has a full outer shell of 8 electrons.

The electron dot structure for cyclopentane (C₅H₁₀) is as follows:

H H
\ /
C─C─C─C─C
/
H

In this structure, each carbon atom is bonded to two hydrogen atoms, and the carbon atoms are connected by single bonds in a cyclical arrangement. The octet rule is satisfied for each carbon atom in the cyclopentane ring.
