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? .what is the formal charge on each atom (excluding h atoms)? . what is the ideal bond angle for the c-o-h atoms? . what is the hybrdization for the c atoms?. are there any resonance structures, yes or no?

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.

is there any options? maybe im just not seeing them but i need the options to
