Question

why alkane is said to be saturated hydrocarbon where as alkene and alkyne are unsaturated hydocarbon...?

Answer 1

Dear, saturated means, “achieved it's limits” and so unsaturated is “not achieved it's limits”. Now, hydrocarbons are the compounds of Carbon and Hydrogen only, in CH4 (an unsaturated hydrocarbon) carbon has reached it's limits to the extent that it can bond to hydrogen (no more than four hydrogens can attach here) so it is a saturated hydrocarbon, however, in unsaturated hydrocarbons, as there are carbon–carbon double/triple bonds which can be broken and consequently more hydrogens can be bonded to it, these hydrocarbons haven't reached their limits of binding to hydrogens, so unsaturated hydrocarbons! Hoping that you got your answer.

❥ HELLO BUDDY ❥

ALKANE ARE SAID TO BE SATURATED HYDROCARBON BECAUSE IT CONTAIN CARBON CARBON SINGLE BOND WHILE ALKENES AND ALKYNES NOT .
