Question

Week I 4 COMPLETE THIS UIZBY OURSELF ( orth 10 pts with % pt b nus), PRINT IT, AND TURN IT IN A OF DISCUSSION WED, APRIL. 26 (Note: "The printer wasn"t working/was out of ink/had a paper jam" is no turning in your pre-lab quiz late. Complete this assigament soon enough that you allow adequate time to print it o. response to The printer malfunctioned" will be "Not my problem." Plagiarizing someone else's answers is academic misconduct and is mot acceptable. T THE BEGINNING se for sta The standard I pts 1. An organic molecule is one that is all-natural contains Carbon only made by living organisms c) 1 pt 2 Glycerol and ethanol both contain as a functional group -OH e) -NH2 a) makes ionic bonds with other atoms 1 pt 3. Carbon almost always b) shares a single electron with another atorm to make a single bond shares four electrons with odher atoms to make 4 covalent bonds 4. A double bond between C atoms is needed to make 1 pt cis-trans isomers )structural isomers c) enantiomers 4.5 pt 5. In the chart below write a "" in the blank if the molecule at the top of the column has the property listed to the left. W in the blank if the molecule lacks that characteristic. Fatty Acid Contains H, C, and O Contains at least one carboxyl group Has a hydroxyl group on all but one of its C's pt 6. A simple monosaccharide would dissolve most readily in water ) salad oil c) gasoline 1 pt 7. A fatty acid contains @ a hydrocarbon b) a carboxyly group c) both a hydrocarbon and a carboxyl group d) neither a hydrocarbon nor a carboxyl group

Answer 1

1. b. contains carbon (C binds with H or O or N)

2. a. -OH (glycerol has three OH group and ethanol has one OH group)

3. c. shares four electrons with others to make 4 covalent bonds (carbon atom completes its octet only by sharing its valence electrons with other atoms forming only covalent bonds)

4. a. cis-trans isomers

5.

	Monosaccharide	Hydrocarbons	Fatty acids
Contains H,C and O	+	- no O	+
Contains atleast one hydroxyl group	+	- (however types of hydrocarbons like lipids contains hydroxyl group but the definitive hydrocarbon only contains C and H)	- (they contains carboxylic acid )
has a hydroxyl group on all but one of its C's	+	-	-

6. a. water (as each molecule having several OH groups that readily engage in hydrogen bonding)

7. a. a hydrocarbon (a straight chain of an even number of carbon atoms, with hydrogen atoms)
