Vitamin is an organic compound whose deficiency in the human body can cause apathy, irritability, and an increased susceptibility to infections. Below is an incomplete Lewis structure, for vitamin . Complete the Lewis structure and answer the following questions. [Hint: Vitamin can be classified as an organic compound (a compound based on carbon atoms). The majority of Lewis structures for simple organic compounds have all atoms with a formal charge of zero. Therefore, add lone pairs and multiple bonds to the structure below to give each atom a formal charge of zero.]

a) 21 bonds , and 4 bonds

b) bond angles , a < 109.5° , b ≈ 120° c < 109.5° d,e < 120° f ≈ 120° g ≈ 109.5°

c) 6 carbon atom are sp² hybridized

d) two carbon atoms are sp³ hybridized,

    two oxygen atoms are sp³ hybridized

    Nitrogen is not sp³ hybridized , it has sp² hybridization

e) vitamin B6 exhibit delocalized bonding, because the three double bond in ring are delocalized over 5 carbon atoms and one nitrogen atom , they are formed due to  6 p orbitals of 5 carbons and 1 Nitrogen atom. The bonding in vitamin B6  is similar to the Benzene.
