    fail + Infinitive

    Dear teachers,

    Would you be kind enough to tell me your opinion concerning the following sentences?

    1.X-ray pattern failed to affirm this suggestion.
    2.Hence m-toluenesulphonic acid fails to rearrange,
    3.Stilbene fails to react with diazoacetic ester.
    4.Gelatin and some of the protamins which do not contain tryptophan fail to respond to the test.

    Thank you for your efforts.

    Regards,

    V.

    Re: fail + Infinitive

    I would suggest for the first one:

    1. The x-ray pattern failed to confirm this suggestion.

    The others sound OK as English, though I haven't a clue about chemistry. ("Arrange" has double "r".)
