chapter 1: review of general chemistry: electrons

Question 1

what was the old definition of an organic compound and inorganic compound

Answer 1

something derived from living organisms

something derived from nonliving organisms

Question 2

what is the difference between organic compunds and inorganic compounds(isolation)

Answer 2

organic cmpds are harder to isolate and purify when heating and they decompose more readily than inorganic compounds

Question 3

what was the idea of vitalism

Answer 3

impossible to convert an inorganic compound into an organic compound without outside force

Question 4

why was the idea of vitalism discarded

Answer 4

german chemist frederick demonstrated the conversion of ammonium cyanale into urea

Question 5

what is the NEW definition of an organic compound

Answer 5

compound that contains carbon atoms

Question 6

what is the NEW definition of an inorganic compound

Answer 6

compound that lacks carbon atoms

Question 7

what is a constitutional isomer

Answer 7

same formula, different physical properties and different names

Question 8

how many bonds can carbon form

Answer 8

4 ( tetravalent)

Question 9

how many bonds can nitrogen form

Answer 9

3 bonds ( trivalent)

Question 10

how many bonds can oxygen form

Answer 10

2 bonds(divalent)

Question 11

how many bonds can hydogen form

Answer 11

1 bond monovalent

Question 12

how do you draw constitutional isomers of small molecules

Answer 12

1. determine the valency of each atom

2. connect the atoms of highest valency and place the monovalent atoms a the periphery

Question 13

how are atoms with high valence connected

Answer 13

they are connected first
