Question

the lewis structure of pentane is shown below. which of the following represents the condensed structural formula corresponding to this lewis structure? h h h h h | | | | | h - c - c - c - c - c - h | | | | | h h h h h ch3(ch2)4ch3 ch3c≡cch2ch3 ch3ch(ch3)ch2ch3 ch3(ch2)3ch3

Explanation:

Step1: Identify carbon - hydrogen groups

In pentane, there are 5 carbon atoms. The terminal carbons are $CH_3$ groups and the internal carbons are $CH_2$ groups.

Step2: Write condensed formula

For a straight - chain pentane with 5 carbon atoms, the condensed formula is $CH_3(CH_2)_3CH_3$. The first and last carbon are $CH_3$ groups and there are 3 $CH_2$ groups in between.

Answer:

D. $CH_3(CH_2)_3CH_3$
