Question

The condensed structural formula for 2,2,3-trimethylbutane is _____. ch3c(ch3)2ch(ch3)2 ch3ch2ch(ch3)c(ch3)3 ch3c(ch3)2c(ch3)3 ch3ch2(ch3)ch(ch3)2

Answer 1

The chemical structure of 2,2,3-trimethylbutane is shown as attached document. In a condensed structural formula, a branched chain is shown in bracket (). 

So according to the chemical structure, the correct condensed structural formula for this molecule is CH3C(CH3)CH(CH3)2
