Question

Hydrocarbons consisting of short carbon chains are ________.

A. more volatile than hydrocarbons with longer chains
B. more viscous than hydrocarbons with longer chains
C. typically stable in a solid-state at room temperatures
D. more prone to tangling and bonding with each other

Answer 1

A

Step-by-step explanation:

Hydrocarbons with short chain lengths are more volatile than those with longer chains. A practical example of this can be seen in the first few members of the alkane series. They are mostly gaseous in nature and this is quite a contrast to the next few members which are solid in nature.

As we move down the group, we can see that there is an increase in the number of solids. Hence, as we go down the group we can see a relative increase in order and thus we expect more stability at room temperature compared to the volatility of the shorter chain
