(A) Teflon is used in nonstick cookwere
(R) Teflon is resistant to attack by corrosive reagent.

(A) : Teflon has high thermal stability and chemical inertness (R) : Teflon is a thermoplastic

(A): Material used in the construction of a standard resistance is constantan or manganin. (R): Temperature coefficient of Resistance constantan is very small.

A : Copper is used for making electric wires. R : Metal with low resistivity behave as good conductors.

(A): Fuse wire must have low resistivity and low melting point. (R): Fuse is used to protect a device connected in series to it from large currents.

The oxidation of aryl methyl or cyclo alkyl methyl by the treatment with chromyl chloride to an aldehyde via the formation of esters is known as Etard reaction. The oxidation stops at aldehyde stage because the product of the reaction is acylal, R - CH(OCOCH_3)_2 which is resistance to oxidation with this reagent. The acylal on hydrolysis gives aldehyde. Which of the other reactions will produce benzaldehyde ?
