Ladies and Gentlemen:

We have acted as counsel to Air Products and Chemicals, Inc., a Delaware corporation (the “Company”), in connection with the registration by the Company under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a Registration Statement on Form S-3 filed with the Securities and Exchange Commission (the “Commission”) on or about the date hereof (such registration statement is herein referred to as the “Registration Statement”), of an indeterminate amount of one or more of the following securities (collectively, the “Securities”), which the Company may issue from time to time under the Registration Statement: (i) shares of the Company’s common stock, par value $1.00 per share (the “Common Stock”), which may include shares of Common Stock issuable upon the exercise, conversion or exchange of the other Securities included in the Registration Statement, (ii) shares of the Company’s preferred stock, par value $1.00 per share (the “Preferred Stock”), which may include shares of Preferred Stock issuable upon the exercise, conversion or exchange of the Debt Securities and Warrants (as defined herein) included in the Registration Statement, (iii) one or more series of unsecured debt securities (the “Debt Securities”) to be issued under the Indenture, dated as of April 30, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee, as supplemented from time to time (the “Indenture”), (iv) warrants (the “Warrants”) to purchase Common Stock, Preferred Stock or Debt Securities, the terms of which will be determined by the board of directors of the Company prior to the issuance thereof, (v) depositary shares, representing a fractional interest in shares of Preferred Stock and evidenced by a depositary receipt (the “Depositary Shares”) and (vi) units comprised of one or more of foregoing securities (the “Units”).

We have reviewed the Indenture and such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. We have assumed that all signatures are genuine, that all documents submitted to us as originals are authentic and that all copies of documents submitted to us conform to the originals.

We have assumed further that any Securities that are issued and delivered, and the issuance thereof, will comply with all requirements and restrictions, if any, applicable to the Company, whether imposed by any agreement or instrument to which the Company is a party or by which it is bound or any court or governmental or regulatory body having jurisdiction over the Company or otherwise.

We have also assumed that the Securities will be offered and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and the appropriate prospectus supplement. We have assumed further that any supplements to the Indenture, warrant agreement, deposit agreement, and unit agreement, as applicable (collectively, the “Documents”), will be governed by and construed in accordance with the laws of the State of New York. With respect to any Document executed or to be executed by any party other than the Company, we have assumed that such party has, or will have, duly authorized, executed and delivered the Documents to which it is a party and that each such Document is, or will be, the valid and binding obligation of such party, enforceable against it in accordance with its terms.
