1a. Determine the (valence) electron count for a molecule with the formula CsH4 b. A skeletal Lewis structure of a molecule with this formula is shown below. How many electrons remain to be distributed after accounting for the electrons used in the skeletal structure? c. Complete the structure by distributing the remaining electrons. Make certain that the total number of shared and unshared electrons shown in the structure matches the valence electron count and the octet rule is obeyed. (Hint: What should be done if you run short of electrons?) Η H-C-C-C-H 2a. Two resonance structures of formic acid that satisfy the octet rule are shown below. Determine the formal charge on each oxygen in the provide space below each structure. Show your work. 20: H-C-0-H H-C=ö-H The Lewis structure of acetone, CsH60, is: HOCH H-C-0-C-H WH What functional group is present in acetone? Refer to the carbon atom labels to answer the following. What is the hybridization of carbon: 1?_ 2? What is the H-C1-H bond angle? What is the C1-C2-Cs bond angle? What is the C1-C2-0 bond angle? Redraw the Lewis structure of acetone as a condensed Lewis structure and in line-angle (line-bond) form.

Answer 1

da Formal charge -> H-c-6-H H-C=O-H Formula for find out the formal charges - (Valence Shell elections of atom) - (Number of bonds Associated with the atom) - (No. of Unshared electron by it)
