Which of the following compounds will undergo Cannizzaro reaction

The unit of rate constant for first order reaction is:

The amine which will not undergo benzoylation in alkaline medium is

Answer the question on basis of passage given below :
Molecular nitrogen is very little reactive chemically. During lightning discharge, atmospheric nitrogen and oxygen combines to form nitric oxide which also combines with oxygen to form nitrogen dioxide. Both NO and \(NO _2\) constitute smog which is very poisonous. It can cause burning sensation in the eyes and adversely affect respiratory system.
What are the constituents of photo chemical smog ?

Which of the following will not be sweet in taste?

\(2 A+B \rightarrow A_2 B\)
For the above reaction, the rate law equation is, rate \(=k[A][ B ]^2\) with \(k=2.0 \times 10^{-6} mol^{-2} L^2 s^{-1}\). If the initial concentrations of \(A\) and \(B\) were \(0.1 mol L ^{-1}\) and \(0.2 mol L ^{-1}\), respectively, the rate of reaction after \([A]\) is reduced to 0.06 \(mol L ^{-1}\) will be

Read the passage carefully and answer the Questions
Aldehydes, carboxylic acids and ketones are widespread in the animal and plant kingdoms.
They play a pivotal role in various biochemical processes of life. Their presence in nature
adds fragrance and flavor. These compounds are widely used in food products, pharmaceuticals, paints, resins and other important product industries. These compounds are prepared by various laboratory methods, which mainly include oxidation, formylation, acylation and reduction. Due to the polar nature of the carbonyl group in aldehydes and ketones, they can exhibit different reactions like nucleophilic addition. They do exhibit redox and various condensation reactions which lead to the formation of various important compounds. On the other hand, the carboxylic acids are mainly prepared by oxidation and hydrolysis of different compounds. The carboxylic acid consists of a carbonyl group and the hydroxy group (attached to the carbonyl carbon atom). This makes it possible for the carboxylic acid to participate in various chemical reactions which involve cleavage of the C- OH bond and the O_H bond along with the reactions involving the complete -COOH group.
The IUPAC name of following compound is
OHC - C₆H₄ - CHO - p

Answer the question on the basis of passage given below :
There are some deposits of nitrates and phosphates in the earth’s crust. Nitrates are more soluble in water. Nitrates are difficult to reduce under laboratory conditions, but microbes do it easily. Ammonia forms a large number of complexes with transition metals. Hybridisation easily explains the ease of sigma donation capability of NH₃ and PH₃. Phosphine is an inflammable gas, and it is prepared from white phosphorus.
Which of the following is the correct statement?

The term "biodiversity" was popularised by:

If the points \((2,-3),(\lambda,-1)\) and \((0,4)\) are collinear, then the value of \(\lambda\) is:

If \(y=38.85+7.64(x-2020)\) is the equation of the straight line trend for the following data:

Year(x)	2017	2018	2019	2020	2021	2022	2023
Profit( Rs. '000) (y)	14	30	26	44	38	56	64

The trend value for the year 2021 by least square method is :

Let \(A=\left[a_{i j}\right]_{3 \times 2}\) and \(B=\left[b_{i j}\right]_{3 \times 4}\) be two matrices.
Then the order of the matrix \(\left(A^T \cdot B\right)^T\) is :
