Chemistry: Hyphen or bond?

[Fred Van Ackeren]

Hi,
The attached sample .jpg. is part of an answer key formatted as exercise material.

I have several questions:

1. The yellow highlighted chemical expressions show what appears to be hyphens, or are they bonds?
2. The bond structures show wavy diagonal lines which are not in my list of symbols.
3. I have elected for the graphic artist to do these bonds electronically unless I can find a way to braille the oval in the first one. OR, should these structures be rendered as graphics?

Thanks,
Fred

Hello, Fred. Your questions are important; I am glad you asked them.

1. YES those short little lines in -OCH3 and -OH are single bonds.

2. Although we are allowed to create symbols when they do not appear in the codes, I think your idea to turn this over to a graphic artist is a good one. The artist should draw the lines, the squiggles, and the circles/ovals just as they appear in print.
