Question

How to do Q43?? Pls explain as I always do these type of questions wrong

Answer 1

your option a) would be correct for sp2 sp2 and sp from left to right
just check the no.of total bonds with C
consider double Bond as a single bond (temporarily) similarly consider triple bond,lone pairs as one bond
if Total bonds are 3 then its sp2 and 2 then it's sp
please note that it's not a standard result.but this surely helps in that kind of problems.

please mark my answer brainliest if this helped you
