Concept explainers
(a)
Interpretation:
The systematic name of the given compound should be identified.
Concept Introduction:
- The first step is to find out the parent chain of the hydrocarbon. Parent chain should contain maximum number of multiple bonds, maximum number of substituents of the
functional group which is used as main suffix. - Other functional group, if any, should be identified and name it as prefix.
- Numbering should be done in such a way that to get the lowest number for suffix functional group, multiple bonds.
- The punctuation used to separate numbers is commas and hyphen is used to separate a number and alphabet.
- If the ‘ane’ ending of the
alkane is replaced by ‘yne’ ending, the name of alkyne is obtained. - Select the longest chain which contain the triple bond in such a way to get lowest value for the functional group.
- Two types of
alkynes will be there according to the position of triple bond. Terminal alkyne is the one which contain triple bond at the end of the chain and internal alkyne is the one which contain triple bond not at the end but present in any other positions in the chain. - When the counting is done from either sides of triple bond in a compound which contain same number for the functional group suffix, the correct name will be the one which have lowest substituent number. In the case of more than one substituent, alphabetical order should be followed.

- at 32.0 °C? What is the osmotic pressure (in atm) of a 1.46 M aqueous solution of urea [(NH2), CO] at 3 Round your answer to 3 significant digits.arrow_forwardReagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…arrow_forwardNonearrow_forward
