Which is a general representation of a secondary amine? A. An N is bonded to two electron dots above; with a dotted triangular line to an H, a solid triangular line to an H, and single line to an H; it is noted that the angle between the last 2 H atoms is 107 degrees.

B. An N with 2 electron dots is linked to an R 1 group with a single line, an H with a triangular line, and and H with a dotted line.

C. An N with 2 electron dots is linked to an R 1 group with a single line, an R2 group with a triangular line, and and H with a dotted line.

D. An N with 2 electron dots is linked to an R 1 group with a single line, an R 2 group with a triangular line, and an R3 with a dotted line.
