Test: IUPAC Nomenclature - JEE MCQ

B.P. ∝ extent of H bonding ∝ surface area of molecule.

Unsaturation means the presence of double bond or triple bond. It is used to calculate the number of rings and pi bonds present in a molecule.
Degree of unsaturation = 11

Allyl isocyanide has the structure
it has and bonds along with 2 nonbonded electrons

More the no. of carbons more will be the heat of combustion.

1,2 -Epoxy propane is the correct IUPAC name of given compound.

The compound is a derivative of benzaldehyde. Start numbering C-atoms of benzene nucleus from C-atom bearing CHO group.

The highest priority functional group is the double bond, and the carbon chain must be numbered such that this functional group is given the lowest number carbon. This is then followed by the lowest numbering of both halogen groups. Therefore, (D) is the correct numbering.

-Dimethylbut-1-ene

Isopropyl group is attached to the propyl group in

methylpentane

The numbering goes as follows.

3,3-diethyl-5-isopropyl-4-methyloctane

The correct name is 3-(N, N-dimethylamino)-3-methylpentane

In allylic halides, halogen atom is bonded to a sp³ hybridised C-atom next to carbon carbon double bond.

As for geometrical isomerism, both substiuents on each doubly bonded carbon should be different so only can show geometrical isomerism. Rest other do not show G.I. as they have same species on same double bonded carbon. For e.g.
