The structure of the compound (1,1-dimethylethyl)cyclopentane is shown in the image attached.
Lewis structure of (1,1-dimethylethyl)cyclopentane
The cyclopentane ring of (1,1-dimethylethyl)cyclopentane, also known as tert-butylcyclopentane, has single bonds between carbon atoms and hydrogen atoms attached to each carbon in its Lewis structure. The cyclopentane ring's tert-butyl group, also known as 1,1-dimethylethyl, is bonded to one of the carbon atoms.
The representation clearly illustrates the molecular connectivity and bonding arrangement in tert-butylcyclopentane by satisfying the octet rule for carbon and the duet rule for hydrogen.
