Question

I dint understand the propane and 2 butane structures from the bond line structure for triple bond why we are writing c and c but not ch and ch in 2 butene

pls explain me step by step plssssss​

Answer 1

Answer:

It's so because in propane carbon have not complete it's octet so we add H to complete it's octet. But in 2 butene the carbon don't need any H, as it have already complete it's octet with other carbon.

Hope it will help you.

Mark as brilliant please

Answer 2

Answer:

Peopene has a double bond because of the following reasons :

• it is an alkene and the number of hydrogen atoms in an alkene is double the number of carbon atoms
• Alkene are also unsaturated so they contain double bond.
• Alkenes are a homologous series of hydrocarbons that contains carbon carbon double bond.

2-Butene molecular formula is: C4H8

and is has one carbon carbon double bond

so as per me the given structure is wrong.
