Question

Write IUPAC name of CH2=CH-CH=CH2

Answer 1

hi ,

here is your answer !!!

CH 2 = CH - CH - CH = CH2

process :-

there is 4 carbon atom

so we use butene

there is Double bond

so we use. "ene "

now , IUPAC name

=> 1, 4 - di- butene .

Answer 2

The IUPAC name of the compound is But-1,3-diene.

• Numbering the given compound from most prior carbon atoms means the atom that is attached to a double bond we get four atoms long chain.
• As this compound contains four carbon atoms so will come.
• Again it contains two double bonds at C-1 and C-3.
• For double bond "ene" will come.
• Hence the IUPAC name of the compound is But-1,3-diene.
