    1-butanol because,In this particular case the molecules are similar,since both substances have a hydroxyl group,thus being able to create H bonds.But in the case 1-butanol,the molecules are linear while 2-butanol is not.This stereochemical difference affect the molecules attract each other.The linear molecules are able to come closer,thus creating stronger bonds .In other words raising the boiling point because a higher amount of energy has to be applied in order for one molecule to obtain enough,to leave the liquid phase.

    Point defects are where an atom is missing or is in an irregular place in the lattice structure. Point defects include self interstitial atoms, interstitial impurity atoms, substitutional atoms and vacancies. A self interstitial atom is an extra atom that has crowded its way into an interstitial void in the crystal structure. Self interstitial atoms occur only in low concentrations in metals because they distort and highly stress the tightly packed lattice structure.

    Some crystalline solids are anisotropic because despite showing periodicity they are not exactly the same in all directions. It all depends on the symmetry of the unit cell of the crystal. If its size in the x, y and z direction is the same, it would be isotropic and anisotropic otherwise.

    All crystalline solids are not anisotropic. Those crystalline solids which are anisotropic, have their atoms arranged and spaced in a different manner in three different planes (X, Y and Z).Therefore, if light is passed through such crystal, it will experience different environments in different directions and hence different refractive indices will be obtained.

    A catalytic reaction which depends upon the pore structure of the catalyst and on the size of the reactant and the product molecules is called shape-selective catalysis. For example, catalysis by zeolites is a shape-selective catalysis. The pore size present in the zeolites ranges from 260-740 pm. Thus, molecules having a pore size more than this cannot enter the zeolite and undergo the reaction.
