(a)
Interpretation:
Condensed formula and line formula for 1-bromo-3-hexyne has to be drawn.
Concept Introduction:
Organic compounds can be drawn from its IUPAC name. Initially, the parent chain is identified from the IUPAC name. After that the carbon chain is drawn with carbon atoms alone. Next step is to add the substituents in the respective positions as indicated in the IUPAC name. Remaining valency of carbon atom is satisfied by adding correct number of hydrogen atoms.
Condensed structural formula is a simplified form of representation of a molecule. This gives the information about all the atoms present in molecule and the atoms are placed in sequential order which gives information about which atom is bonded to other atom.
Line formula is the simplest representation of molecule. Carbon atoms are not explicitly shown in line formula. Intersection of lines and the end point of line are considered as carbon atoms. At the end-point it is understood as methyl group. Heteroatoms and hydrogen bonded to the heteroatoms are shown explicitly.
(b)
Interpretation:
Condensed formula and line formula for dichloroethyne has to be drawn.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Condensed formula and line formula for 2-butyne has to be drawn.
Concept Introduction:
Refer part (a).
(d)
Interpretation:
Condensed formula and line formula for 9-iodo-1-nonyne has to be drawn.
Concept Introduction:
Refer part (a).

- Q5: Label each chiral carbon in the following molecules as R or S. Make sure the stereocenter to which each of your R/S assignments belong is perfectly clear to the grader. (8pts) R OCH 3 CI H S 2pts for each R/S HO R H !!! I OH CI HN CI R Harrow_forwardCalculate the proton and carbon chemical shifts for this structurearrow_forwardA. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
