Following is the formula of a simple sugar. Which of the following functional groups is NOT in such a compound? O || OH H OH OH H | H-C-C-C-C-C-C-OH | | | H 1 1 OH H HH carbobyl (C=O) group O hydroxyl (-OH) group O aldehyde (-CHO) group O thiol (-SH) group hp

Look at the third carbon in the longest carbon chain. To draw the molecule in 3D on a 2D surface (such as paper), the Br could have solid wedge showing that it projects to the back of the molecule (behind the paper/screen), and the methyl group could have a dashed wedge showing that it projects to the front of the molecule (out of the paper/screen). Br True False
