1. A Review of General Chemistry

Give the molecular formula of each compound shown

(g)

(h)

Identify the mistakes contained within the following structures.

(a)

For each of the following line-angle drawings, 

(i) give the number of carbons, 

(ii) label the carbons, 

(iii) tell how many hydrogens are on each carbon, and 

(iv) draw the hybrid structural formula.

(d)

In 1934, Edward A. Doisy of Washington University extracted 3000 lb of hog ovaries to isolate a few milligrams of pure estradiol, a potent female hormone. Doisy burned 5.00 mg of this precious sample in oxygen and found that 14.54 mg of CO₂ and 3.97 mg of H₂O were generated.

b. The molecular weight of estradiol was later determined to be 272. Determine the molecular formula of estradiol.

How many implied hydrogens does each labeled carbon have?

Convert the following hybrid structural formulas into the line-angle drawings.

(b)

Convert the structure into a line-angle structure. Be sure to assignALLnecessary formal and net charges.

How many hydrogens would you expect a 24-carbon compound from each of the following molecular classes to have?

(a) Alkane

How many implied hydrogens does each labeled carbon have?

Convert the perspective formula to a skeletal structure.

Given the following Lewis structure for butane: ${\mathrm{CH}}_3$-${\mathrm{CH}}_2$-${\mathrm{CH}}_2$-${\mathrm{CH}}_3$, which of the following best represents its skeletal structure?

For each of the following molecules, draw one 3-D representation at only the necessary atoms (that is, the ones with four different atoms/groups attached).

(c)

For each of the following line-angle drawings,

(i) give the number of carbons,

(ii) label the carbons,

(iii) tell how many hydrogens are on each carbon, and

(iv) draw the hybrid structural formula.

(c)

Give the molecular formula of each compound shown

(d)

(e)

(f)

How many hydrogens are attached to each of the indicated carbons in morphine?
