${CH}_{3} - C {({CH}_{3})}_{2} - {CH}_{2} - {CH}_{2} - CH {({CH}_{3})}_{2}$

${CH}_{3} - CH ({CH}_{3}) - {CH}_{2} - CH ({CH}_{3}) - {CH}_{2} - {CH}_{3}$

${CH}_{3} - C {({CH}_{3})}_{2} - CH ({CH}_{3}) - {CH}_{2} - {CH}_{2} - {CH}_{3}$

${CH}_{3} - C {({CH}_{3})}_{2} - {CH}_{2} - C {({CH}_{3})}_{2} - {CH}_{3}$

Detailed Solution

On observing the given IUPAC name of the molecule, the parent chain is hexane consisting of six $C atoms$ . The formula for hexane is ${CH}_{3} - {CH}_{2} - {CH}_{2} - {CH}_{2} - {CH}_{2} - {CH}_{3}$ .

There are three methyl groups $(- C H_{3})$ as given in the IUPAC name, two methyl groups at 2^nd position and one at 3^rd position of the carbon chain.

Hence, the structure for 2,2,3-trimethyl hexane is ${CH}_{3} - C {({CH}_{3})}_{2} - CH ({CH}_{3}) - {CH}_{2} - {CH}_{2} - {CH}_{3}$ .
