Question: Q: A group of atoms that results when one hydrogen atom is removed from an alkane is referred to as what?   Read this paragraph and choose the correct option from the provided answers:  An alkyl group is a group of atoms that results when one hydrogen atom is removed from an alkane. The group is named by replacing the -ane suffix of the parent hydrocarbon with -yl. For example, the CH3 group derived from methane (CH4) results from subtracting one hydrogen atom and is called a methyl group. The alkyl groups we will use most frequently are listed in Table 12.4 "Common Alkyl Groups". Alkyl groups are not independent molecules; they are parts of molecules that we consider as a unit to name compounds systematically. Table 12.4 Common Alkyl Groups.   Choices:  - chloride group  - hyrdrogen group  - nitrate group  - alkyl group   A:
Answer:
alkyl group
