Whether / If
Both whether and if are used to introduce a yes/no question:
Examples:
He asked me whether I felt well.
We're not sure if they have decided.
The verb discuss generally takes whether rather than if.
Examples:
We discussed whether he should be hired.
They discussed whether to invest in the new idea.
After Prepositions
Use only whether after prepositions:
Examples:
We talked about whether we should go or not.
I looked into whether he should stay.
Infinitives
Use only whether before infinitives:
Examples:
She can't decide whether to buy the house or wait.
He considered whether to give up the position or quit next year.
Formal / Informal
Generally, whether is considered more formal than if.
Examples:
