(a) two compounds of formula C4H10

(b) two compounds of formulaC2H6O

(c) two compounds of formula C2H7N

(d) three compounds of formula C2H7NO

(e) three compounds of formula C3H8O2

(f) three compounds of formula C2H4O

Step-by-Step Solution:
Step 1 of 3

Solution 28SP

(a)

Count the number of valence electrons in the molecular formula  as follows:

Total valence electrons = 4(4) + 10(1)

= 16 + 10

= 26

So, there are 26 valence electrons.

Now draw one of the skeletal structures of the molecular formula  as follows:

Here, the number of electrons in this structure is 26.

Similarly, draw another possible structure with the molecular formula  as follows:

Here, the number of electrons in this structure is 26.

Therefore, the two compounds with the molecular formula  as follows:

(b)

Count the number of valence electrons in the molecular formula  as follows:

Total valence electrons = 2(4) + 6(1) + 1(6)

= 8 + 6 + 6

= 20

So, there are 20 valence electrons.

Now draw one of the skeletal structures of the molecular formula  as follows:

Here, the number of valence electrons is 16. So, place the remaining 4 valence electrons as two lone pairs on oxygen atom.

Thus, the Lewis structure with the molecular formula  is as follows:

Similarly, draw another possible structure with the molecular formula  as follows:

Here, the number of valence electrons is 16. So, place the remaining 4 valence electrons as two lone pairs on oxygen atom.

Thus, the Lewis structure with the molecular formula  is as follows:

(c)

Count the number of valence electrons in the molecular formula  as follows:

Total valence electrons = 2(4)+7(1) + 1(5)

=8+7+5

=20

So, there are 20 valence electrons.

Now draw one of the skeletal structures of the molecular formula  as follows:

Here, the number of valence electrons is 18. So, place the remaining 2 valence electrons as one lone pair on nitrogen atom.

Thus, the Lewis structure with the molecular formula  is as follows:

Similarly, draw another possible structure with the molecular formula
