I think it's because the covalent bonds are strong, and therefore unreactive to acids & alkalis.

You'd need to get alkanes in gas form to make it react, but you'd still need energy for it to react, like, say, heat perhaps?

Alkanes are unreactive with acids and alkalis because they lack functional groups that can interact with them. Alkanes consist of only single bonds between carbon atoms and hydrogen atoms, making them relatively inert in these reactions. Their lack of polar or charged groups also contributes to their low reactivity.

Alkanes do not react with acids or alkalis, because of their oily nature.

Alkanes do not have a reactive group (e.g. -OH or -COOH or -COOC) so they cannot react with water.

Alkanes are hydrocarbons - they do not have oxygen. An acid or an alkali is determined by their functional groups, H+ and -OH.

If you add an acid to an alkali, the H+ group and the -OH group react with each other and form water.

Alkanes do not have a functional group, so therefore cannot react with an acid or an alkali.

because alkanes are saturated hydrocarbons. they react with aqueous reagents but in vigorous conditions for ex at high pressure and at high temperature.

Can an acid be canceled out by a base?

Acids release hyrogen ions while bases absorb them, thus canceling out the effects of one another.


What are two substances that can be mixed to neutralized each other?

Acid and base can be mixed to neutralize each other as they react and form water and a salt, which results in a neutral solution. Another example is mixing baking soda (sodium bicarbonate) with vinegar (acetic acid), which produces carbon dioxide gas and water, leading to neutralization.

The gas evolved when metals react with dilute acids?

When metals react with dilute acids, hydrogen gas is evolved. This is because metals displace hydrogen from the acid, resulting in the formation of metal salts and hydrogen gas as a byproduct. The reaction can be represented as metal + acid → metal salt + hydrogen gas.
