1. 1,2-Diphenylethyne (Or) Diphenylethyne (Or) Diphenylacetylene
Reason: Here, the two hydrogens in the ethyne are replaced by phenyl groups and there is only one possibility for such replacement, i.e. 1,2-diphenyl, hence there is no significance of numbering.
2. cis-2-Bromo-3-chloro-2-butene
Reason: Here, both the low priority moieties (i.e. CH3 groups) are on the same side of the C=C, that's why cis-configuration is assigned.
3. cis-3-Methyl-3-hexene
Reason: Here, both the low priority moieties (i.e. H and CH3 moieties) are on the same side of the C=C, that's why cis-configuration is assigned
