6.1 - molecules

Question 1

Which molecules are polar?

Answer 1

Hydroxyl, carbonyl, & sulfhydryl.

Question 2

What molecule is nonpolar?

Answer 2

Methyl

Question 3

What molecule has a positive charge?

Answer 3

Amino

Question 4

What molecules have a negative charge?

Answer 4

Phosphate & carboxyl

Question 5

What is an isomer?

Answer 5

Isomers are molecules that have the same chemical formula but different structures/build.

Question 6

What happens during dehydration synthesis?

Answer 6

Water is created from an O & H atom on two different molecules. As they combine, they pull away from the molecules forcing them to merge.

Question 7

What happens during hydrosis?

Answer 7

Water is shoved back into the molecules, causing them to seperate and return to how they were before dehydration synthesis.

Question 8

What is the relationship between monomers and polymers?

Answer 8

Monomers are so small, almost like legos. Together, they create ‘lego’ masterpieces or polymers.

Question 9

Monomers –> Polymers

Answer 9

Dehyrdation synthesis
