# Comment on the paper entitled Limited surface mobility inhibits stable glass formation for 2-ethyl-1-hexanol, published in J. Chem. Phys. 146, 203317 (2017)

## TL;DR

This comment clarifies misconceptions about the applicability of the Coupling Model to 2-ethyl-1-hexanol, addressing previous issues and reaffirming the model's relevance in understanding glass formation.

## Contribution

It corrects prior misunderstandings by demonstrating that the identified problems do not hinder the Coupling Model's applicability to the studied glass-forming liquid.

## Key findings

- The issues raised in the original paper are resolved.
- The Coupling Model remains valid for 2-ethyl-1-hexanol.
- Clarification supports the model's use in glass formation studies.

## Abstract

The authors of the paper, Limited surface mobility inhibits stable glass formation for 2-ethyl-1-hexanol, J. Chem. Phys. 146, 203317 (2017), encountered two problems in considering applicability of the Coupling Model. We show in this Comment that these problems do not exist.
