What happens when you touch two hot bowls made of different materials? The wooden and metal bowl are both at the same temperatur
Julli [10]

Answer:

Explanation:

Both metal and wooden bowls are at the same temperature . But wood is non-conductor of heat whereas metal is conductor of heat .

If we touch the wooden bowl , heat flows from hot to cold object . Since the finger is at higher temperature , heat flows from finger to wooden bowl . But , since wood is non conducting , it does not allow heat to be conducted through it . Hence very less heat will be conducted from our finger .

On the other hand , if we touch a metal bowl , heat flows from finger to the metal bowl , without any hinderance . Hence rate  of heat flow will be fast in case of metal bowl . As a result of it , we feel cool in touching metal bowl . This feeling will be absent in case of wooden bowl.

Draw the structure of the major organic product isolated from the reaction of 3-hexyne with hydrogen (1 mol), Lindlar palladium.
ohaa [14]

Answer:

See explanation and image attached

Explanation:

When 1 mole of hydrogen is added to 3-hexyne, the addition occurs on the same face or side of the triple bond to yield cis-2-hexene in the presence of lindlar catalyst which prevents further hydrogenation. This is known as syn addition.

The syn addition is achieved because the hydrogen molecule is first adsorbed on the surface of the palladium metal and is subsequently attached to the same face of the triple bond in 3-hexyne as shown in the image attached to this answer.
