    Due to less steric hinderence in aldehydes then ketones

    0Thank You

    Nidhi Bharti 3 years, 7 months ago

    Aldehyde are more reactive because in ketone there are 2 alkyl goups which causes more stearic hindrance to the nucleophile but in Aldehyde there is only 1 alkyl group. Also due the presence of 2 alky group, +I effect is more on carbony carbon of ketone which reduces it's electrophilicity

    Preparation of soyabean milk

    • Soak about 100 g of soya beans in sufficient amount of water for 24 hours.
    • Take out swollen soya beans and grind them to a very fine paste with a pestle-mortar.
    • Add about 250 ml of water to this paste and filter it through a muslin cloth.
    • Clear white filtrate is soya bean milk.

    Compare its taste with natural milk.

    • Take 50 ml of natural milk in three beakers and heat the beakers to 30o, 40o and 50o C respectively.
    • Add spoonful curd to each of the beakers and leave the beakers undisturbed for 8 hours and curd is ready.
    • Similarly, take 50 ml of soya bean milk in three other beakers and heat the beakers to 30o, 40o and 50o C respectively.
    • Add 1 spoonful curd to each of these beakers.  Leave the beakers.

    4 undisturbed for 8 hours and curd is formed.

    Type of milk Beaker no Temperature Quality of curd Taste of curd
    Buffalo milk 1 30oC Perfectly dense semi solid Sour
    2 40oC Compartively watery Less sour
    3 50oC Highly watery Tasteless
    Soya bean milk 4 30oC Almost dense Sour
    5 40oC Semi solid little bit watery Sour
    6 50oC High water content Tasteless

    Adsorption is the accumulation of molecular species on the surface rather than in bulk of solid or liquid

    2Thank You

    Rishab Jain 3 years, 7 months ago

    Adsorption is a process in which the particle adsorb (means on the surface not inside the surface) . The particle which is adsorb is called adsorbate . The thing on which a particle get adsorb is called adsorbent . Example-if we dipped chalk in ink and break the chalk then you will see that it is white inside ,and blue on the surface means adsorption takes place

    0Thank You

    Oggy And Jack 3 years, 7 months ago

    Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent.
