The quick answer: that's not true, diols are not as unstable as the textbooks say. Most organic chemistry textbooks say that diols are unstable yet fail to mention that they are unstable in ORGANIC SOLVENTS. in AQUEOUS SOLUTIONS they are much more stable.

HIO4 (periodic acid) is commonly used in organic synthesis to cleave vicinal diols to aldehydes and ketones, a process known as periodate cleavage. This reaction is useful for structural elucidation and for creating synthons in organic transformations. Additionally, HIO4 can be used for oxidative cleavage of double bonds in olefins.
Potassium permanganate (KMnO4) reacts with alkenes through a process called oxidative cleavage. This reaction breaks the double bond in the alkene, resulting in the formation of diols or ketones, depending on the specific conditions of the reaction.
Not sure if it's the main use, but the most common use I have come across is the reaction with osmium tetroxide, where periodic acid is used to cleave the bond between a 1-2 dihydroxy- compound, which is generated bye the reaction between an alkene and osmium tetroxide
1-gem diols have one hydroxyl group attached to a carbon atom, while 2-gem diols have two hydroxyl groups attached to a carbon atom. This difference in structure affects their chemical properties and reactivity. 1-gem diols are more stable and less reactive compared to 2-gem diols due to the presence of only one hydroxyl group. 2-gem diols are more prone to undergo reactions such as dehydration and oxidation due to the presence of two hydroxyl groups, making them more reactive.
When alkenes react with KMnO4, they undergo oxidation to form diols or glycols.

NaIO = Sodium Hypoiodite Sodium (Na+1) + Iodite (IO2-1) Hypoiodite= (IO-1) Na+1 + IO-1 = Na1IO1 but since we dont put a 1 subscript it is NaIO Since iodite lost 2 oxygens and it is a metal and a oxy-radical compound you have to add a hypo- prefix and a -ite suffix, which makes it Sodium Hypoiodite

1,3-diols are organic compounds with two hydroxyl groups attached to a carbon chain, specifically at the 1st and 3rd positions. These compounds have unique properties that make them useful in various applications. They are commonly used as building blocks in the synthesis of complex molecules, such as pharmaceuticals and polymers. Additionally, 1,3-diols can act as chelating agents, forming stable complexes with metal ions. Their ability to form hydrogen bonds also makes them valuable in organic reactions, such as in the formation of cyclic compounds.
Exact chemical mixtures or ratios of chemicals depend on the type of wax, whether they be animal waxes, vegetable waxes, mineral waxes, petroleum waxes, or synthetic waxes. Natural waxes such as animal waxes tend to have a greater variation in wax composition while synthetic waxes generally have less. Chemically, a wax is a type of lipid that may contain a wide variety of long-chain alkanes, esters, polyesters and hydroxy esters of long-chain primary alcohols and fatty acids. They are usually distinguished from fats by the lack of triglyceride esters of glycerin (propan-1,2,3-triol) and three fatty acids. In addition to the esters that contribute to the high melting point and hardness of carnauba wax, the epicuticular waxes of plants are mixtures of substituted long-chain aliphatic hydrocarbons, containing alkanes, fatty acids, primary and secondary alcohols, diols, ketones, aldehydes. Paraffin waxes are hydrocarbons, mixtures of alkanes usually in a homologous series of chain lengths.
Alkenes react with potassium permanganate (KMnO4) through a process called oxidative cleavage, where the double bond is broken and oxygen atoms are added to the carbon atoms. This reaction results in the formation of diols (glycols) or ketones and carboxylic acids, depending on the conditions and the structure of the alkene.

There are many of them, starting with octane, octene, and octyne and their numerous possible isomers; octanols and octane diols and triols; ethyl benzene; dimethyl benzene; etc.
Polyester and polyamide fibers have ester units as their building blocks. Polyesters are formed by the condensation reaction of diols with dicarboxylic acids, while polyamides are formed by the condensation reaction of diamines with dicarboxylic acids.
