Web10 sep. 2014 · We can calculate the number of structural isomers by double bond equivalent i.e by using the formula: 1 + ∑ i n i ( v i − 2) 2 where n repesents the number of atoms i of a given valency, and v i represents these atoms’ valency. Example: C X 4 H X 6: 1 + ∑ i n i ( v i − 2) 2 = 1 + 4 ( 4 − 2) 2 + 6 ( 1 − 2) 2 = 8 − 6 2 + 1 = 2 Web1 mrt. 2024 · In fact, the formula for all alkanes is C n H 2n + 2. You have already seen that butane (C 4 H 10) has an isomer, 2-methylpentane. These are the only two isomers of this molecule. C 5 H 10, on the other hand, has three isomers, while C 6 H 14 has nine.
