    Which of these bonds is weakest? hydrogen or covalent and why ?
    Hydrogen Bonds are weaker than covalent bonds because they do not involve sharing of electrons, and they are weaker than ionic bonds because they involve the attraction of partial (not full) opposite charges.

    look at the information below .. what is true about it ?
    water 4.18, ethyl alchol 2.44,benzene 1.80, sulfuric acid 1.40
    Sulfuric acid is less resistant to temperature change than water., More heat is required to raise the temperature of 1 g of water 1 than to raise the temperature of 1 g of ethyl alcohol 1 ,Water has a high specific heat due to the hydrogen bonding between water molecules, Benzene is more resistant to temperature change than sulfuric acid.
