Amines are basic compounds They act as Lewis base due to the presence of lone pair electrons at nitrogen Amines aho behave as base as well as Bronsted inductive effect, steric hindrance and resosnance. CH_(3)-NH_(2)+HOH hArr CH_(3)-NH_(3)^(+)+OH^(-) CH_(3)-NH_(2)+H^(+)Cl^(-)hArr CH_(3)-NH_(3)^(+)+Cl^(-) Alkyl groups and electron groups hence these groups increases the electron density at nitrogen as well as the basic amines character of amines. Basic character of teritary amines is reduced due to the steric hindrance of three alkyl groups. Experimentally it is observed that stronger bases have smaller values of pK_(b) greater value of K_(b) . Which among hte following is the most basic in aqueous medium?

Festival season is going in Agrabah and the people are going crazy to see various sorcerers, craftsmen etc. who are visiting the city to showcase their magic. A large crowd has gathered around a Card-master who is asking a logical riddle to the crowd. Whosoever succeeds in solving the riddle gets a reward. He arranges the cards of first 20 natural numbers and lists down the difference between two consecutive numbers (value on right card minus value on the left card) of the arrangement, which are 19 in number. The difference is given as -11 8 -7 -2 11 -4 12 -15 11 3 -13 9 -1 -3 6 -10 -3 5 9 The city is beautifully lightened up with candles and diyas and the vibes of happiness and joy were coming from all the directions. Aladdin and Abu are also enjoying the festival when they find a very interesting game of balloons. Inflated balloons are arranged in a straight line and are marked with English Upper case letters. The player can perform the following action any number of times (including zero): Choose any one of the balloons from the straight line and replace the letter on it with any other Uppercase English letter. Note that even if the replaced letter occurs S multiple times, only the chosen occur- rence of this letter is replaced. Find the sum of the minimum number of operations required to convert the given balloon line to balanced ones. Let's call a balloon line balanced if all characters that occur in this balloon line occur the same number of times. Line 1: ABAAACDHIAACKIOA (16 letters) Line 2: BBCABCDFAHABNAJHDYWGEJA (23 letters) Line 3: ABSDJAHSABDJAMDHANDHASAKIABCHD (30 letters)
