on comparing the first group elements for their ionic conductance and mobility. li+ is the most hydrated ion and Cs+ becomes the least. therefore the conductance/mobility decreases down the group. but it is given that li+ has the highest mobility! kindly explain me this sir🙏🏾

    larger the size of the ion lesser will be the mobility

    Here order is given wrong
  • Priyanshu kumar thankyou
    Lesser is the size....more is hydration of the ion which can't move freely...so becomes less mobile

    More mobility of ion means more freely it moves

    yes, Li + has the smallest size while Rb+ has the largest size. small is the size, high is the aquation of ion. so Li+(aq.) size will be high in polar solvents. while Rb+(aq.) size...

    yes here it is given wrong

    Li+ is having the least mobility since it is hydrated to a very larger extend.
