Problem Details

The structures of two isomers of heptane are shown below.

Which of these two compounds would you expect to have the greater viscosity?

The figure shows 2 ball-and-stick structures. Compound A is for CH3CH2CH2CH2CH2CH2CH3 and compound B is for CH3CCHCH3 with 2 -CH3 groups attached to the second (from left to right) carbon and a -CH3 group attached to the third carbon.
