What alkene would you start with if you wanted to synthesize pentane?

Answer 1

Ava Andrews

Either pent-1-ene or pent-2-ene would be used.

You begin with a 5-carbon alkene and work your way up to a 5-carbon pentane.

Pent-1-ene, CH₵CH₂CH₂CH=CH₂, and pent-2-ene, CH₃CH₂CH=CHCH₃, are the possible combinations.

You use a catalyst made of nickel and hydrogen to react with either of these.

The formulas are

H₂ + CH₂ → CH₃CH₂CH₂CH₂CH₃

additionally

CH₃CH₂CH = CHCH₃ + H₂ → CH₃CH₂CH₂CH₂CH₃

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
