Question

Draw the structures of following compounds:
p-Nitropropiophenone

Answer 1

Hint: We have to know that the IUPAC framework is the most reasonable and broadly utilized arrangement of classification in natural science. The IUPAC of any natural compound comprises three sections in particular, word root, postfix (optional or essential) and prefix (auxiliary or essential).

Complete answer:
We have to know that the word root prop recommends that there are three carbon molecules in the parent chain. Which contains the practical gathering ketone from the outset position, the postfix shows that the utilitarian gathering ketone is likewise joined to phenyl bunch and the prefix demonstrates that a nitro bunch is available at para position to the useful gathering.
Therefore, the structure of p-Nitropropiophenone is drawn below,

Additional information:
For $4 - methylpent - 3 - en - 2 - one$ ,
The word root confined recommends that there are five carbon particles in the parent chain, the prefix shows that a methyl bunch is subbed at fourth position. The essential postfix en shows that the parent chain is unsaturated and there is a twofold security (alkene) among third and fourth carbon particles. The optional additional one demonstrates that a ketone is present at the second situation of carbon.

Note:
In the event that two chains of equivalent lengths are conceivable, the one with the bigger number of side chains will be the parent chain. The parent chain is numbered so that the utilitarian gathering gets the least vacant. At the point when an enormous and complex gathering is joined to a benzene ring it is entirely expected to name the particle as an alkane, alkene and benzene as side chain subordinate phenyl.
