doubt that vs doubt whether vs doubt if :

doubt that or doubt whether or doubt if

If you really doubt that something is true (suspect that it’s false), use “doubt that”: “I doubtthat Fred has really lost 25 pounds.” If you want to express uncertainty, use “whether”: “I doubt whether we’ll see the comet if theclouds don’t clear soon.” “Doubt if” can be substituted for “doubtwhether,” though it’s considered somewhat more casual, but don’t use itwhen you mean “doubt that.”
