The value of Kf for water is 1.86, calculated from glucose solution. The value of Kf for water, calculated from NaCl solution will be (M.Wt of NaCl = 58.5 g/mol): - a)= 1.86
- b)< 1.86
- c)> 1.86
- d)Zero
Correct answer is option 'A'. Can you explain this answer?
The value of Kf for water is 1.86, calculated from glucose solution. The value of Kf for water, calculated from NaCl solution will be (M.Wt of NaCl = 58.5 g/mol):

d)
Zero

Anshul Mehra answered |
Ans.
The value of Kf is same as it is a constant. It is only temperature dependent and is independent of the solute.
Therefore, Kf for water for NaCl solution is 1.86.
Therefore, Kf for water for NaCl solution is 1.86.

Edurev.iitjam answered |
To determine which of the compounds is most basic, we need to analyze the nitrogen atoms in each structure and their availability to donate a lone pair of electrons.
The basicity of nitrogen-containing compounds depends on the availability of the lone pair on nitrogen. Nitrogen atoms in aromatic systems, such as pyridine or quinoline derivatives, have lone pairs that participate in resonance, which can reduce their availability for protonation. Nitrogens that are less involved in resonance and conjugation will tend to be more basic.
Analyzing each structure:
- Compound 1: This structure has nitrogen atoms in an aromatic system similar to quinoline. The lone pairs on these nitrogen atoms are somewhat delocalized due to resonance, reducing their basicity.
- Compound 2: This structure is analogous to acridine, which has a nitrogen in an aromatic system. The lone pair is part of the conjugated system, reducing its basicity.
- Compound 3: This structure has a nitrogen in a pyridine-like environment (quinazoline), but its lone pair is still somewhat available, making it relatively more basic compared to compounds where nitrogen is more deeply involved in conjugation.
- Compound 4: This structure is a pyrimidine derivative. The nitrogen atoms are part of an aromatic system where their lone pairs are involved in resonance. Therefore, they are less basic.
Conclusion:
Among the given compounds, Compound 3 (quinazoline derivative) is the most basic because its nitrogen atoms are less involved in resonance compared to the other structures, making the lone pair more available for protonation.
The correct answer is:
Option 3.

Chirag Verma answered |
Out of three terminals probability of selecting terminals of two friends is = 1/3
∴ Probability of not selecting same terminal = 1- 1/3 = 2/3
∴ Probability of not selecting same terminal = 1- 1/3 = 2/3

Pioneer Academy answered |
A low spin complex is formed when the ligands are of strong field strength whereas high spin is characterised by weak field strength.
In K2NiF6 , Ni is in +4 oxidation state with d6 electronic configuration.Here fluoride acts as a strong field ligand resulting in low spin complex.
In a strong field, all of the electrons in d6 are paired up, leaving zero unpaired electrons, corresponding to a zero magnetic moment.
Note: When metal is in +4 oxidation state all ligands act as strong field ligands.
