g) 4-chloropent-1-ene

Or 4-chloro-1-pentene (the former is more correct, though some institutions do accept this as an IUPAC nomenclature)

f) 1,5-dibromo-6-methylcyclohexa-1,3-diene

E) is correct.

F) is 1,4-dichloro-5-methylcyclohexa-1,3-diene. Name the carbon with functional group as Carbon 1 and go clockwise (in this case) where the next functional group is nearest.

Yes I realised too, and bromine positioning is 1,5 not 1,4. Methyl positioning is 6 not 5. Thanks for pointing out

No problem
G) is 4-chloro-pent-1-ene. Find the longest straight carbon chain which is 5 carbon. Name functional group first then the chlorine substituent.
