Question

A uniform electric field having strength stack E with rightwards arrow on top is existing in x-y plane as shown in figure. Find the p.d. between origin O & A(d, d, 0)

  1. Ed (costheta + sintheta)    
  2. –Ed (sintheta – costheta)    
  3. square root of 2 E d    
  4. none of these    

The correct answer is: –Ed (sintheta – costheta)

Oxygen differs from the otehr elements of the group. Compounds of oxygen with metals are more ionic in nature and hydrogen bonding is more important for oxygen compounds. Oxygen is never more than divalent because when it has formed two covalent bonds, there are no low energy orbitals which can be used to form further bonds. However, the elements S, Se, Te and Po have empty d-orbitals which may be used for bonding and they can form four or six bonds by unpairing eletctrons. However, the higher oxidation states becomes less stable on descending the group. p - dpThe bond between S and O or Se and O, are much shorter than might be expected for a single bond owing to p interaction between the p-orbital of oxygen and d-orbital of S or Se.
Which of the following statement is incorrect?
