Question

i. What is the Lewis structure for CH3CHCHOH? (If resonance is present, draw only one structure.)ii. What is the total number of valence electrons? ___________iii.What is the formal charge on each atom (excluding H atoms)? C_______ C_______ C_______ O_______iv. What is the ideal bond angle for the C-O-H atoms? _______________v. What is the hybrdization for the C atoms? C__________ C__________ C__________vi. Are there any resonance structures, Yes or No? _________

Answer 1

Answer:

i: answer is in attachment.

ii: 24 valance electron in overall structure

iii: carbon having positive charge while oxygen having negative

iv: a bond angle of approximately 104.5 degrees.

v:  CH3 having sp3 hybridization  and both CH having sp2 hybridization

vi: yes. resonance occur between CH=CH and oxygen.

Explanation:

iii: oxygen is electronegative so attraction of electrons occur at oxygen results in negative charge.

iv: a bond angle is about 104.5 degrees because the oxygen has 2 lone pairs and 2 bond pairs of electrons so lone pairs repulsion occur more than bonding pairs that's why the angle is less than that of an atom with tetrahedral or pyramidal geometry.
