Final answer:
Nonpolar molecules containing only carbon and hydrogen are part of the hydrocarbon family which includes alkanes, alkenes, alkynes, and arenes.
Step-by-step explanation:
Molecules containing only carbon (C) and hydrogen (H) are typically nonpolar and belong to the hydrocarbon family of compounds. This family includes several subtypes such as alkanes, which have the general molecular formula CnH2n+2 where n is an integer, alkenes with CnH2n, and alkynes with CnH2n-2. Additionally, the family also includes arenes, which are aromatic hydrocarbons like benzene. Hydrocarbons are characterized by their carbon-carbon (C-C) and carbon-hydrogen (C-H) single bonds and show varying characteristics and boiling points based on their molecular size and structure.
Compounds containing only carbon and hydrogen are known as hydrocarbons. Hydrocarbons are a family of organic compounds that include alkanes, alkenes, alkynes, and arenes. These compounds are nonpolar because the carbon-hydrogen (C-H) bond is not very polar due to the similar electronegativities of carbon and hydrogen.
