CHAPTER 3 REVIEW

3.1 – CARBON COMPOUNDS

What is the difference between organic and inorganic compounds? Organic molecules have lots of C in C-H bonds Inorganic molecules have lots of C in C-H bonds. Organic molecules are found only in nonliving things. There is no difference.

HOW MANY VALENCE ELECTRONS IN A CARBON ATOM? 1 2 3 4

How many covalent bonds can carbon form? 2 4 6 8 Why?

How many bonds will oxygen form to be stable? 2 4 6 8 Why?

How many bonds will H form to be stable? 1 2 3 4 Why?

How many bonds will N form to be stable? 1 3 5 7 Why?

The structural formula is showing a: Straight chain Spiral chain Branched chain Ring

The structural formula is showing a: Straight chain Spiral chain Branched chain Ring

The structural formula is showing a: Straight chain Spiral chain Branched chain Ring

The structural formula is showing a: Straight chain Spiral chain Branched chain Ring

The structural formula is showing a: Straight chain Branched chain Highly branched chain Ring

How many carbon atoms are in the structural formula shown? 1 6 7 8

How many hydrogen atoms are in the structural formula shown? 3 5 8 12

How many hydrogen atoms are in the structural formula shown? These carbons are not “full” so H atoms are implied!

In the structural formula, why is the part outlined in red written as -OCH3 and not -OH3C? H only have 1 valence electron and can only bond with one other thing H must always go on the outsides of a molecule It shows the correct connectivity of the atoms All of the above

Identify the functional group in the red box. Hydroxyl Carboxyl Amino Phosphate

Identify the functional group in the red box. Hydroxyl Carboxyl Amino Phosphate

Identify the functional group in the red box. Hydroxyl Carboxyl Amino Phosphate

Identify the functional group in the red box. Hydroxyl Carboxyl Amino Phosphate
