    the energy required to break HB in H2O > the energy released when new bonds btw the haloalkane and water are formed..... So HALOAKANES R NOT VERY SOLUBLE IN H2O...

    Free expansion means the expansion of a gas when the external pressure (pext) ) is zero. So the expansion of a gas in vacuum is free expansion as the external pressure is zero. The work done in the free expansion of a gas is always zero, wether the process is carried out reversibly or irreversibly. Secondly, the free expansion of the gas isothermal if no heat exchange is allowed between  the system and the surrounding that is if the free expansion is carried out adiabatically, then it is isothermal.

    The strength of carboxylic acid can be discussed by positive inductive effect. Here, in ethanoic acid there is an electron releasing inductive effect from the alkyl group. The larger the positive inductive effect, the lesser will be the strength of an acid. Similarly in formic acid there is no alkyl group and hence no inductive effect takes place. So formic acid is a stronger acid than ethanoic acid.

    The negative end of one molecule attracts the positive end of the other and as a result, a weak bond is formed between them. This bond is called hydrogen bond .
    Conditions for hydrogen bonding
    1)The molecule must contain a highly electronegative atom linked to hydrogen atom. The higher the electronegativity, more is the polarization of the molecule.
    2)The size of the electronegative atom should be small. The smaller the size ,the greater is the electrostatic attraction.
