3methylbut1en1yl

3methylbut-1-en-1-yl refers to a specific organic chemical group. It is derived from 3-methylbut-1-ene, which is an alkene with the chemical formula C5H10. The "3-methyl" indicates a methyl group (CH3) attached to the third carbon atom of a four-carbon chain. The "but-1-ene" part signifies a four-carbon chain with a double bond starting at the first carbon atom. The "-1-yl" ending denotes that it is a univalent radical or substituent group, meaning it is a fragment that can form a chemical bond with another atom or molecule.

In this specific group, the double bond is located between the first and second carbon atoms of the butene chain. The methyl group is attached to the third carbon. When this group acts as a substituent, it attaches to another molecule through the first carbon atom, the one involved in the double bond. This structural arrangement influences the chemical reactivity and physical properties of compounds containing the 3methylbut-1-en-1-yl group. It is a type of alkenyl group, characterized by the presence of a carbon-carbon double bond.
