Question

A cube has side 1.2 ´ 10-2 m. Its volume will be recorded as

  1. 1.728 cross times 1 0 to the power of negative 6 end exponent m to the power of 3 end exponent    
  2. 1.72 cross times 1 0 to the power of negative 6 end exponent m to the power of 3 end exponent    
  3. 1.7 cross times 1 0 to the power of negative 6 end exponent m to the power of 3 end exponent    
  4. 0.72 cross times 1 0 to the power of negative 6 end exponent m to the power of 3 end exponent    

The correct answer is: 1.7 cross times 1 0 to the power of negative 6 end exponent m to the power of 3 end exponent


    v equals l to the power of 3 end exponent equals 1.728 cross times 1 0 to the power of negative 6 end exponent
    Length has two significant figure v = 1.7 cross times 1 0 to the power of negative 6 end exponent m to the power of 3 end exponent
    Hence (C) is correct.

    The D, L system of relative configuration is not 100% correct, and hence R, S system was adopted as a defect proof, absolute configuration. The R, S system involves the following steps:
    Step I: The four atoms or groups attached to the chiral carbon atom are assigned a sequence of priorities according to sequence rules.
    Step II: The arrangement of these four atoms is observed by drawing a curved arrow from the atom with the highest priority (1) to the atom with next highest (2) and if the direction of this arrow is clockwise it indicates R configuration, while the anticlockwise direction from group (1) to group (2) indicates S configuration. However, this convention is true only when the atom with the lowest priority (4) is present on the vertical bond, in case of Fischer projection. In case, the atom (4) lies on the horizontal bond opposite configuration is assigned.
    Now observe the monochlorination of 2-chlorobutane.

    Priority order of some groups:
    Cl > CH2CH­3 > CH3 > H; CH2Cl > CH2CH3, CH2CH2Cl > CH3
    Which of the above structures can exit as enantiomers?
