Three examples of molecules whose Lewis structures are exceptions to the octet rule should be given. Concept Introduction: Most of the elements having atomic number below 20 follow the octet rule but there are several exceptions for compounds including: Lithium, beryllium, boron and aluminum. Compounds formed from elements from main group in the third period and below deviate from the octet rule. Molecules with an odd number of electrons disobey the octet rule. .

Question

Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure |N—N=N] : 0: :0-C H .. I :Ö: H 1 O-H + Is the proposed Lewis structure reasonable? 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 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: * * 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 "0,0".
