Question

Which one of the following shows the correct condensed structural formula of n-butane?

• A. $H_{3}CC{H}_{2}C{H}_{2}C{H}_3$
• B.
• C.
• D. None of the above

Answer 1

The correct option is A $H_{3}CC{H}_{2}C{H}_{2}C{H}_3$

a. Omitting some or all of the dashes representing covalent bonds is known as condensed structure.
Indicate the number of identical group attached to an atom by an script.
the condense structure of n-butane is $H_{3}CC{H}_{2}C{H}_{2}C{H}_3$.
b. Expanded structure

c. Bond line structure
