Match the molecules in List-I with the corresponding shape in List-II: List-I (Molecules): (a) $NH_3$ (b) $ClF_3$ (c) $PCl_5$ (d) $BrF_5$ List-II (Shape): (i) Square pyramidal (ii) Trigonal bipyramidal (iii) Trigonal pyramidal (iv) T-shape Choose the correct answer from the options given below:
Which of the following pairs of species have the same bond order?
The number of geometrical isomers shown by [Pt(Py)(NH₃)BrCl] is:
In which of the following compounds is an intramolecular hydrogen bond present?
The electronegativity difference between $\text{N}$ and $\text{F}$ is greater than that between $\text{N}$ and $\text{H}$, yet the dipole moment of $\text{NH}_3$ (1.5 D) is larger than that of $\text{NF}_3$ (0.2 D). This is because:
Match List-I with List-II. **List-I (Compound)** A. $NH_3$ B. $BrF_5$ C. $XeF_4$ D. $SF_6$ **List-II (Shape/geometry)** I. Trigonal Pyramidal II. Square Planar III. Octahedral IV. Square Pyramidal
