(a) and (b) are the same compound (3-methylpent-2-ene) with C₂H₅ $>$ CH₃ at C-3; (c) is hept-2-ene; (d) and (e) are the same compound (3-bromo-2-chloropent-2-ene) with Cl $>$ CH₃ at C-2 and Br $>$ C₂H₅ at C-3

(a) and (b) are different compounds; (d) and (e) are different compounds

(a) and (b) are the same (3-methylpent-2-ene) with CH₃ $>$ C₂H₅ at C-3; (d) and (e) are the same with CH₃ $>$ Cl at C-2

(c) is hex-2-ene; in (d)/(e) C₂H₅ $>$ Br at C-3
