of 28 > Classify each statement about saturated and unsaturated hydrocarbons as true or false. True False Aromatic hydrocarbons that contain a benzene ring readily undergo addition reactions, whereas alkenes do not. Answer Bank Benzene is nonpolar and insoluble in water. The boiling point of straight chain alkanes generally decreases as molecular size increases. Alkanes and alkenes are both Inpolar. kenes are soluble in other hydrocarbons. Alkenes are insoluble in water, whereas alkanes are soluble in water

Part II. True or False (16 pts) 1. CH3CH2CH2CH2 is the formula for a saturated hydrocarbon. 2. The physical properties of alkynes are very different from those of alkenes. 3. 2-butyne can exist as cis- and trans-isomers. 4. Only alcohols contain an oxygen bearing functional group. 5. Replacing the O with an S in the following compound converts the compound to a thiol. 6. The boiling point for ethers should be much higher than alkanes of similar formula mass. This...

Classify each of the statements as true or false. True False Answer Bank The entropy of a substance increases when a liquid vaporizes to a gas at any temperature. Entropy decreases as the temperature increases. An exothermic reaction is always spontaneous. Product formation is always favored in a reaction with a negative AH° and a negative AS. For an endothermic reaction, a decrease in temperature results in a decrease in the equilibrium constant. A reaction will have an equilibrium constant...

Classify each of the statements as true or false True False Answer Bank Marginal utility is always positive. Numerical utility values are relatively easy to calculate. Diminishing marginal utility means that consumption of an additional unit decreases utility. Marginal utility is the extra satisfaction experienced by one additional unit of consumption Marginal utility is always negative. Utility is a measure of the satisfaction people receive from their choices If you eat a slice of pizza that gives you food poisoning....

Classify each statement about effective nuclear charge, Zeff, as true or false Effective nuclear charge is dependent on the number of electrons present in the atom In a Be atom, a 1s electron has a greater Zeff than a 2s electron Across a period, as Zeff increases atomic size decreases Electrons in a p orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge A 1s electron in a Be atom has a...

Classify each statement about effective nuclear charge, Zeff, as true or false. True False Effective nuclear charge is dependent on the number of electrons present in an atom. In a N atom, a ls electron has a greater Zer than a 2s electron. Electrons in a p orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge. Als electron in a B atom has a smaller Zeff than a ls electron in a...
