3. A graduated cylinder has lines every 1 ml. Draw a small portion of a graduated cylinder (draw it in the space below) with this precision, using the numbers between 80 ml and 90 ml. Draw liquid on your drawing so that the meniscus reads 84.8 ml. Explain why you can read this measurement as 84.8 ml and not 84 ml and not 84.86 ml.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
