Melting point of product (C) = \(142\degree\;C\)
Hence, the correct option is (D): \(142\degree C\)
Convert Ethanal to But-2-enal
Write structure of the products of the following reactions: 
In the given figure, the blocks $A$, $B$ and $C$ weigh $4\,\text{kg}$, $6\,\text{kg}$ and $8\,\text{kg}$ respectively. The coefficient of sliding friction between any two surfaces is $0.5$. The force $\vec{F}$ required to slide the block $C$ with constant speed is ___ N.
(Given: $g = 10\,\text{m s}^{-2}$) 
Two circular discs of radius \(10\) cm each are joined at their centres by a rod, as shown in the figure. The length of the rod is \(30\) cm and its mass is \(600\) g. The mass of each disc is also \(600\) g. If the applied torque between the two discs is \(43\times10^{-7}\) dyne·cm, then the angular acceleration of the system about the given axis \(AB\) is ________ rad s\(^{-2}\).

Carboxylic acid makes up a series of fatty acids that is essential for human health. Some carboxylic acids such as omega-6 and omega-3 are not produced in the human body. This carboxylic acid helps in maintaining the cell membrane and control nutrient use along with metabolism. It is essential to consume those foods which have fatty acids.
