Select the ion having p pi-dpi bond :

Compare the acidic strength of the following (a) CHF_(3) (b) CHCl_(3) (c )CHBr_(3) (p pi - dpi " bonding in Br is not as much as effective as in Cl due to large size of Br ")

Find the area of the shaded region in Fig. 3, where arcs drawn with centres A, B, C and D intersect in pairs at mid-points P, Q, R and S of the sides AB, BC, CD and DA respectively of a square ABCD of side 12 cm. [Use pi=3.14]

A uniform rod AB of mass m and length l is at rest on a smooth horizontal surface. An impulse J is applied to the end B , perpendicular to the rod in the horizontal direction. Speed of particlem P at a distance (l)/(6) from the centre towards A of the rod after time t = (pi m l)/(12 J) is.
