Concept explainers

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

Question

What is not correct about alkanes

a. They have relatively high boiling points

b. They have relatively low boiling points

c. They are hydrocarbons

d. They contain a lot of energy

Definition Definition Simplest organic compounds that contain only single bonds between carbon – carbon atoms and carbon – hydrogen bonds. This means they are a series of saturated compounds with a general molecular formula, C n H 2n+2 .
