I.U.P.A.C NAME OF

CH_2 = CH-(CH_3)_2​

Answer 1

Answer:

The IUPAC name of CH2=CH−CH(CH3)2 is 3-methyl- 1-butene as the parent chain has four carbon atoms with C1=C2(lowest numbering to the double bond) and one methyl substituent at C3. Was this answer helpful?

Answer 2

IUPAC name of $\bf CH_2=CH-(CH_3)_2$ is 2-Methyl-1-propene.

JUSTIFICATION

• $\sf CH_2=CH-(CH_3)_2$ contains 3 carbon atoms. So, the root word is 'Prop'.
• First carbon has a double bond, so the nature of bonding is '1-ene'.
• At the second carbon, the substituent group $\bf CH_3$ is attached. Thus the prefix should be 2-Methyl.
