Circle the letter of the correct answer. Which of the following compounds is saturated? propene octane 3-heptyne 2-butene 1-butene Which formula represents an alkyne? C_5H_8 C_5H_12 C_5H_16 C_5H_10 What is the total number of covalent bonds in a molecule of C_4H_10O? 10 12 14 16 18 What is the name of the alkyl group containing three carbon atoms? diphenyl trimethyl propyl methyl butyl What is the IUPAC name of the following molecule? 2-bromo-4-isopropyl-3-methylbutane 2-bromo-3, 5-dimethylhexane 3, 4-dimethyl-2-bromohexane 2-bromo-3-methyl-4-propylbutane 2-bromo-3, 5-dimethylheptaneExplanation / Answer
a) In organic chemistry, a saturated compound is a chemical compound that has a chain of carbon atoms linked together by single bonds.
Hence, correct answer is (b) octane
b) The general chemical formula of alkyne is CnH2n2
Here all options have C=5, so H = 2*5 - 2 = 8
So, the correct answer is (a) C5H8
c) C4H10O is n-butanol. Four Carbon atoms are bonded with 3 covalent bonds with one another, and two of the C atoms are bonded with 6 Hydrogen atoms
by 6 covalent bonds, and one C atom is bonded with 2 hydrogen atoms with 2 covalent bonds and one C atom is bonded with one H atom and one O atom,
the O atom is also bonded to one H atom by covalent bonds.
So, in total, there are 14 covalent bonds. Answer is (c) 14
d) Propyl is a three-carbon alkyl substituent with chemical formula –CH2CH2CH3 for the linear form. Answer is (c) propyl
e) Answer is (b) 2-bromo-3,5-dimethylhexane
