Answer the questions in the table below about the shape of the sulfur hexabromide (SB) molecule. How many electron groups are around the central sulfur atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central sulfur atom? (You may need to use the scrollbar to see all the choices.) (choose one) x 5 ?

Hydrogen bonds are noncovalent interactions between a hydrogen atom with a partial positive charge, called the hydrogen bond donor, and an atom with a partial negative charge, called the hydrogen bond acceptor. Progesterone is a hormone that contains two ketone groups. The oxygen in the ketone group can function as a hydrogen bond acceptor. н, со CH, Select the amino acids that have side chains that can form a hydrogen bond with progesterone at pH 7. tryptophan...
