Which of the following is not an intra molecular redox reaction?

The roster form of the set A = {x : x N, x < 8} is

Roster form gives us list of all elements of the sets. Set builder form gives the details of the set in compact form.

The appropriate reagent for the following transformation is:

The oxidation number of Pt in  is

A particular emission line, detected in the light from a galaxy, has a wavelength , where is the proper wavelength of the line. The galaxy distance from us

Identify the set from the following which cannot form acetone in a single –step reaction

 (A) is:

A beam of light AO is incident on a glass slab in a direction as shown in figure. The reflected ray OB is passed through a Nicol prism on viewing through a Nicole prism, we find on rotating the prism that

  The products (A) and (B) are:

 The products (B) and (C) are:

If Z = aX + bY and r is the correlation coefficient between X and Y, then  is equal to -

The imaginary part of is-

If the lines and are concurrent, then the value of l is

A: The product of the perpendiculars from
B: The product of perpendiculars from (1,1) to the pair of lines
C: The product of perpendiculars from (0,0) to pair of lines
D: The square of the distance from (0,0) to the point of intersection of Arrange A,B,C,D in ascending order

If the equation represents a pair of straight lines, then the square of the distance of their point of intersection from the origin is

denotes a pair of straight lines, then the point of intersection of the lines is
