Provide an acceptable name for CH3CH2CH2C(CH3)2I?

Question

The last character is a capital "I" (eye)

Answer 1

2-Iodo-2-methylpentane. The longest chain in the compound is CH3CH2CH2-C-CH3, so that's pentane. The -C- carbon atom is second from one end, so that's position 2. It has a CH3 and an I on it, so 2-iodo-2-methyl. In Geneva IUPAC names, substituents are in alphabetical order in English.
