how do we determine if an element has single,double or triple bond?

Dear student
Please find the solution to the asked query:

Among elements Nitrogen forms a triple bond with another Nitrogen atom and Oxygen forms a double bond.
These can be known by writing down the electron dot configuration of the atoms and seeing how they use these bonds to complete their octet.

In case of Carbon compounds however:

A compound with the general formula CnH2n+2 is known as an alkane and an alkane  does not have any double bond.
{here, n is the number of Carbon atom, for example CH}

A compound with the general formula CnH2n is known as an alkene and has a double bond.
for example Ethene, C2H4]

A compound with the general formula CnH2n-2 is known as an alkyne and an alkyne  has a triple bond. for example
Ethyne, C2H2
