In the structure of the title compound (NP2MBA), C14H13NO, the conformation of the C—O bond is syn to the ortho-methyl substituent in the benzoyl phenyl ring, while the N—H bond is anti to the ortho-methyl substituent. The structure of NP2MBA closely resembles that of 2-chloro-N-phenyl­benzamide, with similar bond parameters. The dihedral angle between the phenyl and benzoyl rings is 88.05 (5)°. Mol­ecules are linked into a chain through N—H⋯O hydrogen bonding.

In the structure of the title compound (N2CPBA), C13H10ClNO, the conformation of the N—H bond is anti to the ortho‐Cl substituent in the aniline benzene ring. It closely resembles the structure of 2‐chloro‐N‐phenylbenzamide (NP2CBA), although the two amides crystallize in different crystal systems. The molecules of N2CPBA are linked into a chain through an N—H...O hydrogen bond.

The conformation of the NH bond in the structure of the title compound (N34DMPBA), C15H15NO, is anti to the meta-methyl substituent in the aniline ring, similar to that observed with respect to the meta-chloro substituent in N-(3,4-dichloro­phen­yl)benzamide (N34DCPBA), but in contrast to the syn conformation observed with respect to the meta-methyl substituent in N-(3,4-dimethyl­phen­yl)acetamide. The bond parameters in N34DMPBA are similar to those in N34DCPBA and other benzanilides. The mol­ecules in N34DMPBA are packed into a column-like structure in the direction of the a axis through N—H⋯O hydrogen bonds.

The structure of the title compound, C14H13NO, resembles those of N-(2-chloro­phen­yl)benzamide, 2-chloro-N-phenyl­benzamide, N-(2,3-dichloro­phen­yl)benzamide, N-(3,4-dichloro­phen­yl)benzamide and 2-chloro-N-(2-chloro­phen­yl)benzamide with similar bond parameters. The benzene and methylphenyl rings have a dihedral angle of 63.41 (5)°, while the amide group makes a dihedral angle of 20.5 (1)° with the benzene ring. The mol­ecules are linked into chains in the b-axis direction by N—H⋯O hydrogen bonds.

In the mol­ecular structure of the title compound, C16H17NO, the two aromatic rings are close to orthogonal to each other [dihedral angle 78.8 (1)°], while the central –NH—C(=O)– amide core is nearly coplanar with the benzoyl ring, forming a dihedral angle of 3.5 (2)°. Inter­molecular N—H⋯O hydrogen bonds in the crystal structure link the mol­ecules into infinite chains running along the c axis of the crystal, and a C—H⋯O interaction also occurs.
