Which one of the following molecules are chiral? please help with 20-23
Which one of the following molecules is chiral? Hydrocarbons containing carbon-carbon triple bonds are called _____. A) alkenes B) aromatic hydrocarbons C) olefins D) alkanes E) alkynes When a neutron in the nucleus is converted to a proton, which of the following is emitted? A) alpha particle B) neutron C) positron D) beta particle E) deuteron Which of these nuclides is most likely to be radioactive? A)^243_95 Am B)^39_19 K C)^209_83 Bi D)^27_13Al E)^127_53 IExplanation / Answer
20 Ans is E
in order for a molecule to be chiral, the carbon must be asymmetric ie. different substituents
21 ans is E
triple bonded compounds are called alkynes
Double bonded compounds are alkenes
Single bonded compounds are alkanes
22 ans is D
0n1 0p1 + -1e0
23 ans is A
The nuclei of all elements with atomic numbers greater than 83 are unstable. Thus all isotopes of all elements beyond bismuth in the periodic table are radioactive.
