Question

Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure Is the proposed Lewis structure reasonable? Yes. O No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are: Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are: Yes No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the O C-O octet rule. The symbols of the problem atoms are:* I * If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "O,O"

Explanation / Answer

(a)

The structure of HBr is correct.

(b)

The structure of HCN is not correct. It has the the right number of valence electrons but does not satisfy the octet rule. The symbols of problem atoms are C and N.

(c)

The structure of CO is not correct. It has the the right number of valence electrons but does not satisfy the octet rule. The symbols of problem atoms are C and O.
