Select saturated hydrocarbons from the following: |
\[{{\mathbf{C}}_{\mathbf{3}}}{{\mathbf{H}}_{\mathbf{6}}};\,\,{{\mathbf{C}}_{\mathbf{5}}}{{\mathbf{H}}_{\mathbf{10}}};\,\,{{\mathbf{C}}_{\mathbf{4}}}{{\mathbf{H}}_{\mathbf{10}}};\,\,{{\mathbf{C}}_{\mathbf{6}}}{{\mathbf{H}}_{\mathbf{14}}};\,\,{{\mathbf{C}}_{\mathbf{2}}}{{\mathbf{H}}_{\mathbf{4}}}\]. |
Two elements 'A' and 'B' belong to the 3rd period of Modern periodic table and are in group 2 and 13 respectively. Compare their following characteristics in tabular form: |
(a) Number of electrons in their atoms |
(b) Size of their atoms |
(c) Their tendencies to lose electrons |
(d) The formula or their oxides |
(e) Their metallic character |
(f) The formula of their chlorides |
(a) Draw a ray diagram to show the refraction of light through a glass slab and mark angle of refraction and the lateral shift suffered by the ray of light while passing through the slab. |
(b) If the refractive index of glass for light going from air to glass is 3/2, find the refractive index of air for light going from glass to air. |
