What would

[jack]

Are these correct? If not, why?

1. What would we do if he did that? (Correct/)
2. What would we do if he does that? (Incorrect?)

3. What will we do if he did that? (Incorrect?)
4. What will we do if he does that? (Correct?)

Are these correct? What do they mean?
5. What would we do if he had done that?
6. What would you have done if he had done that?

Do the conditional rules apply for questions as well?

Thanks.

Many would say that 2 & 4 are wrong because they do not follow the standard pattern. Questions should follow the same patterns. 5 is OK, but I would say 'would we be doing' to show that it is an imaginary present result of an imaginary past action.

4. What will we do if he does that? (Why is this one not okay? The tenses are all correct?)

Thanks.

Sorry- I mean 2&3.
